The DTG’s UK UHD Forum has staged a second 4k Plugfest with an emphasis on content streamed in 4k over satellite, IP and DTT to UHD TVs and set-top boxes.
The event brought together platform operators, TV manufacturers, audio-video content providers and broadcasters, equipment manufacturers, and retailers to investigate HEVC UHD interoperability.
Tests were carried out on a range of 4k receivers, both integrated TVs and set-top boxes, which represented the available receiver market in 2013 and 2014. New 2015 models and prototypes from leading silicon vendors were also tested.
Broadcasters, satellite operators, test labs and test equipment providers contributed UHD HEVC test signals encoded in main and main 10 profiles, covering a variety of resolutions, frame rates, bit depths and colour space, delivered to 4k receivers via USB, modulated as satellite and DTT signals and using MPEG-DASH.
Simon Gauntlett, chief technology officer at the DTG, said: “This second UHD plugfest signals the DTG and the UK UHD Forum’s continued resolve to practical industry collaboration for the launch of robust 4k TV services in the UK.”
Device manufacturers and the DTG’s testing partners were joined during the day by observers from the UK broadcast platforms to assess the state of the technology’s development.
The previous Plugfest, held in October 2014, looked at the interoperability of HDMI connection with 4k and DTG Testing has now launched an HDMI interoperability testing service.
It says many of its testing customers have found that HDMI compliance and certification does not guarantee that licensed CE devices will function correctly and be fully interoperable with other HDMI licensed devices.
